LOUVER PANEL: CONSTRUQTION Filed July 17, 1959 Patented July 15, 1941 UNITED STATES PAT ENT F F 'HQE 2,249,3 6] LoUvEn PANEL'CONSTRUCTION Lloyd M. Jones, Fort Lauderdale, Fla. Application July t, 1939, Serial No. 284,989 ZClaims. 401. 189-62 This invention relates to a louver 'panel construction which comprises a panel or frame adapted to be rigidly secured in an opening in a'building under construction or one previously constructed; and in which frame a plurality of pivoted'louvers may be detachably secured. .The aim is to'provide a construction of this kind in which the. frame or panel may first be rig-idly secured in the opening of the building, and later the-louvers and associated 'parts'may'be detachablysecuredto th'epanel. This arrangement obviates the dangerof'injury to the "pivoted louvers and associated parts while the panel. is being placed in position .or inthe case of anewbuilda ing while construction is in'pro'gress, and it 'a1so enables the louvers and the parts connected therewith to be assembledandriveted together before being mounted in the frame,iwh ich great 1y simplifies the assembling operations. 7, Also the louvers may be painted before being secured to the'panel in the building, and also they may ,be removed for cleaning and painting when desired. The foregoing and other advantages are derived .from the invention, which'is illustrated in one specific'form in ing, in which: s v

Figure 1 is a front elevation of a panel'c'ontaining the present improvements;

Figure 2 is a vertical broken section on the line 2-2 of Figure 1;

Figure 3 is a horizontal broken section on the line 3-3 of Figure 1; and

Figure 4 is a partial horizontal section of a modified arrangement.

Referring to the drawing in detail, my improved construction embodies a panel or frame having a transverse top member Ill, a transverse bottom member H and side members l2, which are secured together at their ends in any suitable manner to form a rigid frame. The louvers [3 are arranged between and pivotally connected to the side members l2 in the manner later described.

The frame or panel made up of the side members I 2 and the top and bottom members l0 and H, is designed to be rigidly secured in an opening in a building, and this may be accomplished by means of nails or other suitable fastening devices l4 driven through said members and into the wall of the building surrounding the frame or panel. Where my improved construction is applied to a new building having a coating of stucco or. the like, spacing strips or shims may be inserted between the side members 12 and the adjacent wall of the building and the the accompanying dr'awfastening nails driven through such, shims, so that in applying the stucco it may be pressed in between the frame or panel and the wall, as indicated at I 6, to produce a tight joint and to assist to firmly hold the frame in position.

Each of the side members l2 of the panel or frame is provided along-itsfront or outer edge with a lateral'flange' IZA, preferably extending from the top to the bottom thereof." The louvers l3 are pivotally secured at, each, end to an L shaped supporting bar ll, each of which is provided with a lateral flange HA and a rearwardly extending flange B, to the latter of which the louvers are pivotally connected as indicated at NC. The-lateral flanges l'lA overlap and are arranged outside ofthe front flanges lZA of the side members l- 2, andthiese flanges I2Aand 'l'l'A are detachably secured together by means of short bolts l8," which may be readily removed or inserted as desired. Along their rear edges thelduvers [3 are pivotally connected to a' com-- mon operating bar [9, by which the louvers are caused to openfand suitable means may be employed for moving saidbar. .f 'Iheside members"l2 are also preferably pro vided alongftheir rear edgeswith lateral flanges I2B, to which ajw'indow screen indicatedat' -S maybe secured, as by means of bars Zil'and 2 bolted or otherwise secured to the flange IZB and between which the screen is held. It will be noted that the flanges |2B are positioned directly back of the joints between the ends of the louvers and the flanges HB, and said flanges MB in conjunction with the bars 2| act as troughs to catch and conduct downwardly any water that may be driven inwardly past the ends of the louvers.

The arrangement shown in Figure 4 is substantially the same as that illustratedin the other figures, so far as concerns the means for detachably securing the louvers in place. In this form, however, the side member I2 is provided with a simple lateral flange I 20 which is bent along its edge to form a trough to conduct away water as previously described.

From the foregoing it will be seen that the invention provides a construction by which the panel or frame may first be mounted in an opening in a building,'either an old building or a new building under construction, and thereafter the louvers and associated parts may be mounted in the frame. This permits assembling and riveting together of the louvers and associated parts before they are attached to the frame orpanel.

close simultaneously. Any

The louvers may be painted before they are placed in position, and they may be removed for cleaning, repainting or repair when desired and again placed in position without disturbing the frame or panel.

Although the invention has been illustrated and described herein as applied to a vertical wall, and certain portions of the device have been indicated as being top, bottom, and side members, it will be realized that the invention contemplates the use of the structure in horizontal or inclined walls and in rotated or reversed positions wherein the stated members or elements will occupy other positions with relation to each other with a corresponding change of designation; all of this without departing from the scope of the claims appended hereto.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a building construction of the class described, a louver panel arrangement for an opening in the wall of an enclosure, said arrangement comprising, in combination, a fixed frame including a pair of side frame members secured rigidly and relatively permanently within, and against the margins of, said opening, said fixed side frame members being substantially of channel shape, each having its web parallel with and adjacent to the sides of the opening, and its flanges extending into the opening, a removable louver frame comprising spaced side frame members of angle shape each disposed with one of its flanges overlapping and closely adjacent to one of the flanges of its associated fixed side member, the other flange of the side frame member of the removable frame being disposed within the confines of the fixed frame and extending parallel with and spaced from the web of the fixed side member, louvers secured at their ends to the last named flanges of the side frame members and means detachably securing said first named flnages of the removable side frame members to the adjacent flanges of said fixed side members, said means being the sole means for attaching the louver frame to the fixed frame, the other flanges of said channel shaped fixed side members being each formed with a flange directed forwardly toward the first named flange of the fixed side member to form a trough which is spaced rearwardly of the joints between the removable frame and the fixed side members, and between the louvers and the side frame members to which they are attached, to catch and divert any water which might pass through said joints.

2. In a building construction of the class described, a louver panel arrangement for an opening in the wall of an enclosure, said arrangement comprising, in combination, a flxed frame of the same outline as said opening and secured rigidly and relatively permanently therein, said frame comprising top and bottom members and a pair of side members, said side members being substantially of channel shape, each having its web parallel with and adjacent the sides of the opening and its flanges extending into the opening, a readily detachable, louver carrying sub-frame comprising spaced side frame members of angle shape each disposed with one of its flanges extending parallel with and closely adjacent to one of the flanges of its associated fixed frame side members, the other flange of said sub-frame side member extending transversely of the opening, within the confines of the rigid frame, parallel with and spaced from the web of said fixed frame member, louvers pivotally secured at their ends to said last named flanges of the sub-frame members, and means detachably securing said first named flanges of th removable side frame member to the adjacent first-named flanges of said fixed frame members, th other or second flanges of said channel shaped fixed frame members being formed with a third flange directed toward the first named flange of the fixed members to form a trough which is spaced rearwardly of the joints between the removable and fixed frames and between the louvers and the side frames to which they are attached, to catch and divert any water which might pass through said joints, said third flange of each fixed side, member also provided with a fourth flange, which is parallel with said second flange and extends away from the web of the channel member, and a screen secured to said fourth flange and extending across the opening.
